Diamond Optics 1.1 decodes diamond cut quality without Wi-Fi, cloud accounts or third-party servers. Enter table percentage, depth, crown angle, pavilion angle, girdle thickness and culet—the diagrams redraw on your device in real time. The optical model grades brilliance (white light return), fire (colored dispersion flashes) and scintillation (sparkle movement) using algorithms derived from gemological research.
Version 1.1 refreshes the workbench interface and enhances on-device proportion tools. Load seeded profiles like Ideal Round, Modern Ideal or Tolkowsky bench, then compare your draft against them side-by-side with percentage-difference breakdowns. Study Hearts and Arrows overlays to see if crown and pavilion mains align into eight-heart and eight-arrow symmetry patterns—the ultimate mark of precision cutting.
Export a proportion sheet summarizing all measurements, performance scores and polish/symmetry notes. No account, no data upload, no subscription wall. Diamond Optics runs entirely on-device, so you own your work and your privacy.
The Diamond Optics team focuses exclusively on cut-quality education tools. This workbench translates gemological formulas into visual, interactive diagrams so students, enthusiasts and professionals can explore how tiny proportion changes shift optical performance. All grading figures are educational estimates—not certified lab grades—and the app clearly disclaims that it does not replace a laboratory report or constitute a buying recommendation.
Top and side views redraw instantly when you adjust table, crown or pavilion. See how facet angles change the profile silhouette and face-up pattern.
Three optical performance bars backed by gemological models. Each metric scores 0–100 with color-coded badges (green Excellent, yellow Good, red Poor).
Load Ideal Round, Modern Ideal, Tolkowsky bench, Shallow, Deep, Thick Girdle, Nail-head, Fish-eye—plus fancy shapes (Princess, Emerald, Oval, Cushion, Radiant, Pear). Compare your draft against any preset.
Black-background circular diagrams showing eight arrows (table view) and eight hearts (pavilion view). Bench alignment score tells you if your proportions fall into the H&A sweet spot (55.5–57.5% table, 33.2–35.5° pavilion, 50% stars, 75–80% lower halves).
Tap carat chips to see face-up diameter scaled against an 18 mm blank. Depth percentage shifts the visual size slightly—taller crowns yield smaller apparent diameter at equal carat weight.
Search or scroll through terms: Table, Crown, Pavilion, Girdle, Culet, Bezel, Star, Lower Half, Polish, Symmetry, Brilliance, Fire, Scintillation. Each entry pairs a geometric icon with a plain-English definition.
